A refrigerator that efficiently cools multiple cold spaces at different temperatures with one compressor and one condenser is disclosed. Multiple, fan equipped evaporators are in series, and an expansion valve regulates superheat from inlet to outlet of the series evaporators. Cold space temperatures are regulated with an on-off thermostat in each space. If only one fan is turned on, system performance approaches that of a single evaporator refrigerator with controlled superheat. More than one evaporator fan may be turned on for initial cooldown. |
